High-Current DC to DC Solid State Relay – 75VDC, 500A / 1000A with Heat Sink
Ultra-high current DC solid state relay designed for demanding DC switching applications, featuring MOSFET output, optical isolation, and low on-state voltage drop.
This high-power DC to DC solid state relay (SSR) is engineered for extreme current switching in industrial DC systems. Using a MOSFET output stage with optical isolation, it delivers fast, silent, and highly efficient switching without mechanical wear.
Designed for applications such as battery systems, energy storage, DC motor control, power distribution, and industrial automation, this relay supports very high load currents while maintaining minimal conduction losses.
The sealed industrial housing, integrated LED status indication, and compatibility with external heat sinks make it suitable for continuous duty in harsh environments.
